Babies can get teeth earlier than expected simply because tooth development and eruption timing vary from child to child. Most babies get their first tooth around 6 months, but some start before 4 months, while others may not get a tooth until after 12 months. In rare cases, a baby is born with a tooth. (nhs.uk)
Early teething is usually not a sign that something is wrong. Genetics and the position of the developing tooth are thought to play an important role, although the exact cause of very early tooth eruption is not always known. (Cleveland Clinic)
Several factors may be involved:
|
Possible factor |
What it means |
|---|---|
|
Genetics |
Early tooth eruption may run in families. |
|
Tooth development |
Some babies' teeth naturally develop and move toward the gums earlier. |
|
Individual growth |
Every baby's development follows a slightly different timeline. |
|
Rare medical conditions |
Certain genetic or endocrine conditions can sometimes be associated with unusually early teeth. |
|
Natal teeth |
A small number of babies are born with teeth already visible. |
Importantly, researchers have not confirmed one single cause of early tooth eruption. For babies born with teeth, a tooth germ positioned close to the gum is one of the most accepted explanations. (Cleveland Clinic)
Usually, yes.
The American Academy of Pediatric Dentistry says the first teeth generally erupt at around 6 months, but some babies may have teeth at birth or develop them during the first month. Teeth present at birth are called natal teeth, while teeth appearing during the first 30 days are called neonatal teeth. (AAPD)
A baby with early teeth may simply be developing faster in this area. Early teeth do not necessarily mean the baby will have stronger teeth or develop permanent teeth earlier.
If your baby starts teething early, focus on comfort and oral care:
Give the baby a safe teething toy to chew.
A refrigerator-cooled teething ring may help soothe sore gums. Do not freeze it. (nhs.uk)
Once the first tooth appears, start brushing it regularly with an age-appropriate toothbrush and fluoride toothpaste. (nhs.uk)
If a tooth is very loose, unusually shaped, or makes breastfeeding difficult, ask a pediatric dentist to check it. Natal and neonatal teeth sometimes have limited root development and can occasionally cause feeding problems or tongue irritation. (AAPD)
Bottom Line
Early teething is usually a normal variation in baby development. Genetics and the position of the developing tooth may contribute, but there is no single proven cause. If a newborn has a tooth or a tooth appears unusually early, a pediatric dentist can determine whether it needs observation or treatment.
Is it normal for a baby to get teeth at 3 months?
Yes. Although most babies start teething around 6 months, some begin before 4 months. (nhs.uk)
Can a baby be born with teeth?
Yes. These are called natal teeth. They are uncommon; one recent analysis estimated about 1 in 289 newborns worldwide has natal teeth. (Cleveland Clinic)
Does early teething mean my baby is advanced?
Not necessarily. Tooth eruption varies naturally between babies and does not by itself indicate that a baby is more developmentally advanced.
Should I use a teething toy for an early-teething baby?
Yes, a properly designed, age-appropriate teething toy can give babies something safe to chew and may help soothe their gums. (nhs.uk)
When should I see a dentist?
The AAPD recommends establishing a dental home within six months of the first tooth appearing and no later than 12 months of age. (AAPD)
